RESUMEN
Survey of sanitation conditions by qualitative sanitation measurement were carried out in three districts, Chachoengsao Province, Thailand. The sanitation of each household was assessed in terms of positive stool examination and scores of seven main sanitary activities which were used to classify each household's sanitation as hygienic or non-hygienic. Stool collections were made from each household's housewife and examined for pathogenic bacteria and parasites. It was found that in the qualitative measurement of the household's sanitation as hygienic or non-hygienic, most sanitary activities were highly associated with the results of stool examination. From consideration of the sensitivity, specificity and kappa coefficient of significant sanitary activities as predictors and the result of stool examination was used as gold standard, it was apparent that a package of all main sanitary activities was the most appropriate measurement in the survey to assess sanitation conditions in the community.
